Product Information

Full details

The Freefoam Fascia Board Double End Corner (600mm x 45mm) is designed for professional contractors and DIY enthusiasts installing PVC fascia systems who need a clean, finished appearance at external corners. Its primary benefit is providing a seamless aesthetic while concealing the essential 10mm expansion gap required for thermal movement. A notable caveat is that proper installation requires a specific combination of adhesive and low modulus silicone to ensure the joint remains functional throughout changing temperatures.

FAQs

Why is the 10mm expansion gap necessary?

PVC expands and contracts significantly with temperature changes; without this gap, the boards may warp, buckle, or pull away from fixings.

Can I use standard wood glue for this trim?

No, you should only use adhesives compatible with PVC and recommended sealants to ensure long-term bonding and movement allowance.

Do I need to fix both sides of the corner trim?

No. One side must be glued to the board, while the other side must be sealed with low modulus silicone to allow for thermal movement.

What tools do I need to cut this trim?

A standard hacksaw or a fine-toothed wood saw is sufficient for clean, accurate cuts.

Is this trim suitable for internal corners?

This product is specifically designed as an external corner trim for fascia applications.

What is 'low modulus' silicone?

It is a type of sealant that remains softer and more elastic than high-modulus alternatives, making it ideal for joints that need to move.

Troubleshooting

Trim is buckling or warping

Ensure that one side of the joint is free to move and only secured with flexible low modulus silicone.

Visible gaps appearing after installation

Verify that the initial 10mm expansion gap was not exceeded during the base fascia board installation.

Trim is difficult to cut without jagged edges

Use a fine-toothed saw and ensure the trim is clamped firmly before making the cut.

Pros and Cons

Pros

Provides a professional, flush finish at building corners
Essential for maintaining structural integrity of PVC fascia installations

Cons

Requires both adhesive and silicone for correct installation
Not suitable for load-bearing applications
Must be cut precisely to match the specific corner angle

Setup, Compatibility & Care

To install, first ensure the fascia boards are installed with the required 10mm spacing. Measure the corner trim against your specific roof height and trim to size using a fine-toothed saw to prevent splintering. Apply a high-quality adhesive to one side of the corner and secure it to the fascia board. On the opposing side, apply a bead of low modulus silicone. This specific type of sealant is critical, as it remains flexible over time, allowing the trim to move as the building shifts. For maintenance, a simple wipe down with a mild detergent and water is usually sufficient to maintain the finish.
